What’s the answer to number 6 ty!!
cluponka [151]

Answer:

0.00032 M

Explanation:

From the question,

Applying the for pH

pH = -log[H⁺]............... Equation 1

Where H⁺ = Hydrogen ion concentration of Hydrochloric acid

Given: pH = 3.50

Substitute into equation 1 and solve for H⁺

3.50 = -log[H⁺]

Taking the log inverse of both side,

H⁺ = 10⁻⁽³⁵/¹⁰⁾

H⁺ = 0.00032 M

Hence the H⁺ of Hydrochloric acid is  0.00032 M

Which statement best describes the motion of
Veseljchak [2.6K]

The dye molecules  move in a directed way from high to low  concentration

Explanation:

The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion:

  • diffusion is the movement of molecules of a substance from one position to another.
  • diffusion occurs from a region of high concentration to that of a low concentration.
  • the dye in the water solution causes an increase in concentration of an area where it is dropped.
  • this causes the particles to spread outward in the solution.
  • a concentration gradient is set up between the two parts of the solution.
  • this gradient facilitates the movement of the dye particles.
